The previous review led to the Leichhardt, Carnarvon and Warrego highways increasing from 100km/h to 110km/h and reducing the speed on the Scenic Highway between Yeppoon and Emu Park Road to make the hilly route safer.

Speed limits were increased on Waterworks Road at Red Hill, Ashgrove and The Gap; Beenleigh-Redland Bay Road and Narangba Road.

Opposition main roads spokesman Andrew Powell said the LNP would ensure police and road safety engineers assessed the speed limits on shortlisted roads to protect community safety.

"Queenslanders will be encouraged to nominate speed limits for review because they are the ones who drive these roads every day," Mr Powell said.

"Depending on the outcome of the review, a road's speed limit can either increase, decrease or stay the same."

Mr Powell said in some cases, a stretch of road may increase and decrease to create a standard limit.

The next election is due by May, but there is speculation is could be held later this year.
